Could humans at any point in history, given the right information, construct an electronic communication network? To test this hypothesis, Substitute Materials will attempt to build a functional electric battery and telegraph switch from materials found in the wilderness, using no modern tools except information from the internet. The telegraph will be a first step towards an ahistorical internet.

This software allows you to get a visual representation of an analog signal using Arduino and Processing. The resolution is 10 bits so this is not like a real oscilloscope but it is still pretty useful. It works by sending values read from the Arduino board (pin 0) to Processing through serial communication.
